[Prior art]
Conventionally, when a DVD or the like on which a movie is recorded is played using the playback device, a plurality of operation buttons recorded on the DVD are displayed on the display, and this is an operation panel provided on the remote control or the playback device. A predetermined function is selected by selecting with the above operating device.
[0003]
For example, when a menu display key provided on the remote controller is pressed, a menu display separately recorded on the DVD is displayed overlaid on a video such as a movie originally displayed on the DVD. Therefore, the user selects this menu by using the cursor keys or number keys on the remote controller, thereby enabling the predetermined functions of the DVD (for example, Japanese-English display, presence / absence of subtitles, the number of playback sound channels). Selection).
[0004]
By the way, recently, in order to improve the operability in a video reproduction device having this type of display, the use of a touch panel has been proposed. In particular, in a vehicle-mounted device such as a DVD car navigation system that requires a safe and reliable operation, the user can directly touch the menu display on the display rather than operating the remote control or the operation panel while looking at the display. Since the operability is better when the desired menu is selected, the use of a touch panel in addition to the remote control and the operation panel of the device is being studied.
[0005]
In addition, since the display of menus recorded on DVDs is premised on the common use of all playback devices, there are certain restrictions on the display content, and not many functions can be selected. Absent. In particular, a menu dedicated to a specific video playback device cannot be dealt with only by displaying a menu recorded on a DVD, and requires a dedicated menu display. In such a case, it is also required to perform display using a touch panel in addition to display using a DVD.
[0006]
In particular, in an in-vehicle device, since an installation space is limited, it is desired to make an operation panel other than a display as small as possible. Applications other than DVD reproduction, such as opening and closing of air conditioners and windows, etc. It is assumed that even control related to the overall functions of the vehicle is displayed on a display as necessary, and is selected by a touch panel, a remote controller, or the like.

[0008]
In this case, the problem is that the display position of a menu or the like recorded on the DVD differs depending on the type of DVD used. DVDs on which data such as movies and car navigations are recorded have different types and numbers of menus to be displayed depending on their uses and manufacturers, and their display positions are often different on the top, bottom, left and right of the display.
[0009]
On the other hand, since the display displayed on the display for using the touch panel is a display dedicated to the playback device, it has been conventionally displayed at a predetermined location on the display. However, since the display position on the DVD varies as described above, if the display for the touch panel is displayed uniformly at a certain position, the display position recorded on the DVD or the like overlaps with the visibility. The operability has deteriorated.
